My invention 'relatesto burners for use in thehandling of liquid and gaseous fuel. It

pertains particularly to burners of the type employed in furnacesunder-boilers in the generation of. steam.

It is an object of the invention to provide a burner structure through whichthe proper mixturejof the fuel with the air and steam may be made so as to accomplish thejnost a efiicientcombustion of the fuel and obtain the desiredheat under the boiler.

I tively Fig. 2 is a side elevationthereof.

The invention residesin the construction; I of the burner'whereby theamount of 3 11', "steam or fuelmay'be varied to accompl1sh the most efiective results.

Said ring may I be clamped in any adjusted position longitudinally' of the burner bodyto'regulate the intake of air to the burner. With p articular reference to Figs. l and 3, it will be noted that the side walls of the casingare approximately parallel between their ends but the I forwardend is tapered toward thedischarge' I op'ening8, which projects into the fire box.

(This opening 10 on each sideof the circular'portion ofthe burnerprovides ample-space for the entrance of air about the fuel dischargeiiozzle. The ring: 5' acts tocontrol the air enter: ing at 10.

IWith reference particularly to Fig.8 theregis a assage indicated in the chamber 12 leading from an'inlet port 13-by Way'of the chamber 12 to a discharge port 14, throughiwhich the trance about'the discharge nozzle 15.
